Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Resource management error

EUVDB-ID: #VU22704

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2019-11135

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the TSX Asynchronous Abort (TAA) in Intel CPUs. The TAA condition, on some microprocessors utilizing speculative execution, may allow an authenticated user to potentially enable information disclosure via a side channel.

Mitigation

Install updates from vendor's website.

2) Heap-based buffer overflow

EUVDB-ID: #VU25510

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2020-1711

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to a boundary error in the way the iSCSI Block driver handles a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an "iscsi_co_block_status()" routine. A remote authenticated attacker can trigger heap-based buffer overflow and cause a denial of service condition or potentially execute arbitrary code with privileges of the QEMU process on the host.


Mitigation
